To all whom it may concern:

- Be it known that LJOI-IN BIAGEEyLOltlZQIl of the United States ofAmerica, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Soot- Blowers for ater-Tube Boilers, of which-the following is a specification, reference being had therein to the accompanying drawings.

In water tube boilers having inclined sets of water tubes such, for example, as what are known as Stirling typeboilers, thereare certain places in the boiler in 'whichthe temperature is necessarily close to that of the combustion'chamber. In such places it is more or less diflicult to maintainfixed soot blowers or cleaners without rapid deterioration or without the use of water. jacketed walls or like protected constructions ers having. upper and lower members connected by water tubes anddivided by baffles so disposed that thetube space is sep arated into passes that ccnductthe gases of combustion around and through the boiler fromthe combustion chamber to the stack.

A feature of the blower is the disposition of jetting members normally exterior to the boiler along the hotter passes working in conjunction with fixed jet tubes arranged" across the cooler portions of the tube spaces.

Another feature isthe'construction of the jetting means for the hotter passes whereby it isreadily mounted in the p j p from the fire room fioor.

The invention consists in the matters hereinafter setfforth, and more particularly pointed out in the appended claims.

Inthe drawings, Figure l, is a view in elevation of a boiler equipped with a blower that embodies features of the invention; Fig;

2is an enlargedview in detail of:a header for the hotter portions of the tubespace or passages; Fig. 3'is a View in detail of a preferred form of construction of the header;

F ig.4 is a view in detail showing the dispo-,

sition of the header in a different position with a corresponding modification of the jet nozzles, and Fig. 5 is a view in detailof a rotary fixed header.

In the drawings, a boiler having a lower member 1 andupper members 2, 3 and 4 connected by a series of water tubes 5, 6 and- 7, is arrangedwith the usual exteriorboiler V bular arms 13is disposed This invention relates to blowers for boil- 7 spring keepers.

setting of the setting 8 and baflies 9 and 10, whereby the tube space of the boiler is divided into the usual passes leading from thejcombustionj v chamber 11 to the back connection for the stack. v The boiler that is herein illustrated isof the usual Stirling type. I V N v Aheader 12 with inwardly extending tuon the exterior of the setting transversely to the initial set 5 of the water tubes in suitably disposed tubular housings l4inserted'in the masonry. A steam line 15 is connected control valve 16 with a telescoping of the header which permits of normal retraction of the latter well into thehousings 14, under the influence of spring nem two or more of which are in compression between the caps 19 of the housings and the header l2,the arms 13 affording convenient Suitable'means, such as the packing gland 20, prevent leakage around through a suitable intake 17 r '70 V oerslS the telescoping intake. Oscillatory jet nczzlesj2l are appropriately mounted on the bracket head22 ofthe arm 13 with suitable connections to a common operating; member inward against the ,retractive effect of thesprings 18, the soot along tubes is dislodged and carried along by the. draft or else is deposited on the fire grates.

As shown in Figs. 1 and 2, the header 12 1s disposed atright angles to the water tube 5and the jet nozzles 21 are accordingly'arv ranged to swing in planes perpendicular to the axis of. the header 12. Ifhowever, it"is preferred to mount the housings 14 so that the header holds a different relation to the tubes, the movement of the jet nozzles 21, in planes parallel to the water tubes is 0-badjacent-bank (5r waand between the l 23 that ismounted on theheader 12 and may tained by appropriately adjusting the connections between the nozzles or nipples and the tube arms 13. Forexampleythe housings may be set in the horizontal courses of the masonry as indicated in Fig. 4, and in such instance the axes of motion of the nipple are disposed substantially perpendicularly tothe plane of the direction of length of the water tubes. course, the'noz'zles can be of any type preferred which will enable the operatorjto project jets of steam across the tubes andsweep the jets back and Y forth in planesparallel to'the tubes. This maybe done by direct movement of the'nozzlesor by the employment of slotted open? ings with stops in the openings to deflect the 25, as, for example, seen in Fig. 4, whereby the jets follow the general direction of the tubes, is readily obtained, the link 28 being given the necessary conformation to obtain this result.

. means,

, jet pipes Qne or more other headers dependent upon the size and arrangement of the boiler, maybe employed to clean-the water tubes and surfaces of theboiler that are in contact with gases ofcombustion in the hotter portions of the'passes. Where, as indicated in Fig. 1, such additional header or headers are arranged at a distance above the floor, a rod 31 and suitable handle 32 may be used for ease of manipulation. If, -to avoid long branches of the steam line, the controlling valve 16 is at a height above the floor, a depending cable or chain or other suitable indicated at 33, may be employed.

Inthe cooler passes of the boiler rotatable or headers that are indicated in end elevatlon at '34, are journaled in the setting across the natural spaces of the'boiler and are provided withjet openings that project the jets against and between the adjacent tubes and along the same and they also sweep the surfaces of the bafiles 9 and 10 and other interior surfaces of the boiler. The rotatablejetheaders may be of any preferred construction and are shown in one form in Fig. 5 with end bracket 35, bearing 36, andje't' nozzles 37. They may be of course dry jacketed, water jacketed, sheathed or otherwise protected against the heat which 1 they are forced'to encounter from the pass-.

ing gases. Controlling valves 88 and chains 39 for manually turning these headers from the blower enable them to be directed as desired to sweep and clean all the surfaces against which the jets may be directed therefrom. I

As a result of this construction, ablower is obtained which readily cleans any of the portions of a boiler of the type indicated. By proper manipulation-of the jetting headers in succession, the soot which is dislodged nearest the fire box or combustion chamber first may be caused to follow the general direction of draft and be blown generally toward the stack although such method of mounting of the jetting headers or members and their normal retraction (except when in active operation) from the path of the proclucts of combustion, avoids the serious effect of heat on theparts and permits the use of members not jacketed or otherwise'protected by a comparatively expensive construction from the effects of the heat. 7

Obviously, changes inthe details of construction may be made without departing from the spirit of my invention and I do not care to limit myself to any particular form or arrangement of parts.

That I claim is 1. The combination with a water tube boiler of the Stirling type of a blower comprising horizontally disposed jet pipes rotatably mounted across some of the passes and adapted to direct jets between and over the water tubes thereof and the surfaces of the boiler that are in contact with the gases of combustion, and headers on the exterior movable toward the interior of the boilersetting, transversely disposed to the adjacent water tubes and each provided with a set of jetting means adapted to be manipulated when the header is moved toward the interior of the boiler setting for sweeping 'across and longitudinally of the tubes. 2. A blower for a water tube boilerhaving top and bottom members, water tubes connectingthe members and baiiies dividing the space of the tubes into passes, comprising rotatable jetpipes mounted across some of the passes and adapted to direct jets between and over the water tubes thereof and the surfaces of the boiler that are in contact with the gases of combustiomheaders transversely disposed to the adjacent water tubes of other passes on the exterior of the boiler and adapted to be steam projected toward the interior of the boiler setting, a series of jetting means on each header adapted when the latter is moved toward the interior of the boiler setting to direct ets of steam across, betweenand along the tubes in the general direction thereof, means for controlline the rotatable pipes and means exterior to theboiler for operating each series of jetting means.

In a water tube boiler having top andthe exterior of the path of flow of gases in the boiler, when the blower is inactive, and to automatically extend into operative relation to the water tubes and surfaces of the boiler that are in contact with the gases of combustion when cleaning fluid under pressure is introduced into said headers, a series of jetting means on each of said headers adapt ed to sweep the water tubes and surfaces of the boiler that are in contact with the gases of combustion when oscillated and manually operable means exterior to the boiler for controlling and directing the series of side headers and for manually operating and controlling the rotatable header.

4. The combination with. a water tube boiler having top and bottom'members connected by water tubes and provided with baffles that divide the tube space into passes together with a setting therefor, of a blower having rotatable jet pipes journaled across certain of the passes of the boiler and adapted to direct jets between and over the water tubes and surfaces thereof that are in contact with the gasesof combustion and exterior headers mounted in the boiler setting and each provided with a series of jetting means adapted to be moved with the headers toward the interior of the boiler setting, together with manually operable means both for manipulating the rotatableheaders and for directing the jet producing means of the side headers to sweepthe water tubes and surfaces of the boiler in contact with the gases of combustion in planes substantially parallel to the direction of length of the tubes thereof.

5. In a water tube boiler having top and bottom members connected with water tubes disposed in series and provided with baffles dividing the tube space into passes, a blower Copies of this patent may be obtained ,for
